Which chemical element has the lowest boiling point?

The element with the lowest boiling point is helium. Helium has the lowest boiling point because it consists of simple, monatomic molecules with weak intermolecular forces. These weak forces make it relatively easy for helium atoms to separate and transition from a gaseous state to a liquid state. Consequently, helium undergoes boiling at an extremely low temperature of -268.93 degrees Celsius, or -452.07 degrees Fahrenheit, making it the element with the lowest boiling point.
